Feb 16, 2018· Features of the MQ sensors. Most sensors of the MQ series operate with working voltages that are typically at 5V, and have a lower absorption of 1 watt (5V here means less than 200 milliampere); such an absorption is mainly due to the heating element drawing power. As for some MQ sensors, the heater is powered at 2V: a low and atypical voltage ...

May 06, 2021· The heater should warm the sensor, after 5 or 10 minutes the metal of the sensor should get warm. The 'signal path' is like this: 5V to both 'A' pins -> 'A' to 'B' is the sensor -> both 'B' pins to resistor and to analog input -> resistor to ground. Also, 22k is very high. The output could be at the maximum. I would suggest to use 2k2 to start ...
